It is certain that the first four spots in WA have gone to Joe Bullock (ALP) and David Johnston, Michaelia Cash, Linda Reynolds (Liberal Party), however it's the distribution of preferences for the final two places that has candidates on tenterhooks.

ABC election analyst Antony Green says it will be another week before the final result is known.

"What the AEC have to do is data entry for all the below the line votes and they have to get them all into the computer system and verify them and once that's done they can set a quota and do the distribution of preferences," he told Geoff Hutchison.

"Our senate calculator was showing Wayne Dropulich (Australian Sports Party) and Scott Ludlam from the Greens winning the last two spots, it's now giving the fifth seat to Zhenya Wang from the Palmer United Party and the sixth to Louise Pratt from the Labor Party."

"It's a very close count, 100 votes either way can trigger that sort of change."

"The cut off points on these are so close that those below-the-line votes will matter."

In addition to the Australian Sports Party being a contender for a seat despite garnering only 0.22 per cent of the above-the-line vote, Antony Green says the count is showing a number of other interesting patterns.

"The other oddity in the count is the Shooters and Fishers Party have consistently improved their vote amongst postal votes and other declaration votes."

"The Liberal Democrats, who have clearly been confused with the Liberal Party amongst votes in every state, are doing very well in postal and pre-poll votes."

"The Palmer United Party has done very badly in votes cast before the election date, clearly their surge came right at the end with a lot of advertising, and they didn't do well beforehand."

It's an anxious wait for Louise Pratt, who is the second candidate on the ALP ticket, and Greens senator Scott Ludlam, to know if they will retain their seats.
